WEATHER-STRIP ATTACHMENT.

Application led March 12, 1927. Serial No. 174,914.

My invention aims to provide an improved weather strip attachment for hinged French windows, shutters andthe like.

One of the objects of the invention is to produce a weather strip attachment which is automatically projected into contacting relation with a French window sill upon closing provide improved means for operating the same. i

Other advantages of my invention will appear in the specification when considered in connection with the accompanying drawing, wherein I have illustrated a preferred form thereof, and in which,

Figure 1 is a fragmentary perspective view of a French window having my improved weather strip attachment secured thereto;

Figure 2 is a fragmentary longitudinal sectional View of the device shown in Figure l. and showing the weather strip engaging the sill ot the window.

Figures 3, 4 and 5 are sectional views taken on the lines 3 3, 1 1 and 5 5, respectively, of Figure 2.

. Figure 6 is an end elevation of the device 4,sho-wn in Figure 1.

Referring specifically to the drawings and to the illustrated form of the invention shown therein.` I have provided a housing casing 10, preferably of sheet metal, and conveniently made like a long, hollow rectangular box to form a housing for the mechanism and for a weather strip operated thereby. which is adapted to be projected into engaging relation with the window sill or the like. To provide means for securing this casing or housing to the lower portion of the `window, I have shown a series of holes for receiving screws, bolts, nails or the like.

Within the housing 10, I provide a iianged sheet metal plate 11 adapted to engage the face'of the window and having the anges at. itsupper side and at Yits ends engaging the inner wall of the housing inside the row 'of holes, thereby providing a stop for the housing when it is secured to the window, and aV separate wall to which various pivot pins and the like may be secured.

As best shown-in Figures 4 and 5, the lower portion of the housing is open and the weather strip plate 12 is mounted therein so that it may be retracted into and projected from the housing. Herein the plate 12 is shown as being made of sheet metal, although it is understood that suitable felt otally connected to the muster means of a bent flat strip 18a having a U-V or rubber material may be applied to its lower edge if it is so desired.

A part of my invention consists of improved mechanism for projecting and retracting the plate 12 automatically from and into the casing incident to movements of the window or other hinged shutter. To this end, I have shown a flat master lever 13 (see Figure 2)V arranged substantially vertically and pivoted to swing about its central portion on a suitable pin, bolt or rivet adapted for the purpose. This lever is shown as connected to lift or project the plate 12 upon movement in one direction or the other, as the case may be. I have shown in the drawings (see Figure 2) a pair of bell crank levers in the form of plates 14 hinged within the housing. and cooperating with suitable projections 15 near the opposite ends of the plate 12. the bell crank plates having slots 16 to permit the necessary swinging movement thereof. Each ot the bell crank lever plates is connected by pivoted links 17 to the master lever 13. The distances from the piv-ot-al point of the master lever to the pivotal connection of the links 17 thereon are equal, so that the movement of the bell crank plates will correspond and be in the same direction.

For actuating the mechanism just described, automatically upon closing the window or shutter to which my improved weather strip is attached. I have shown a rod or operating arm 18 (see Figure 2), pivlever 13 by shaped end portion'presenting holes through which the rod projects, and a shock absorbing spring 18b surrounds the rod in the U- shaped end. This prevents overstrain or breakage in case the arm is adjusted to project the shutter too far or the plate strikes an obstruction.

On the end of the rod 18, I have shown an adjustable head 19 arranged to project from that end of the housing where it will engage and be actuated by coming in contact with the window jamb or door casing. as the case may be. Herein, the headed end of the operating arm 18 is screw-threaded thereon, so that it may be adjusted to move the master lever more or less as it is desired to project the plate 12 a greater or less distance from the casing to engage the window sill.

It is now clear that the mechanism just described will function to project the plate into "'f-rictional Vengagemei'it -With a Window r sill'to prevent rain or cold air'irom entering the house. To retract the plate l2 automatically fromiengagementavithrthe Window sillv upon opening movement, I provide a spring 20 Which coacts Withiithefmasterilever 13, and is secured to a stationarypart of the casing. I have shown the'upper y'end oit' the lever 13 as having an oii'set ear to -receive ahooked end of the .spring-although it may he otherwise engaged, and-1 theupper 'flange of 'the 4plate l1 has an interrupted f portion -to provide -room 4for*thefspringto fWork. As best 'shownin Figure Q, thepup- .per flange of the inside'plate ill hasa. series or' openings vto receivelthe l'otherhooked end of fthe., spring Q0, althoughl it .is `understood 'that the sp-ring may be otherwise. connected -to`;the casing.

VFrom t-heiforegoing"description, it WilIbe -seenthat the securing zbolts, screvvs 'orfthe like, are ,i so arranged vthat they *.Will not linteifere fwith the` Vmovement of the `p'late l2. "Moreoveigithe-plate is shown as .heilig so -shape'dthat thepivot pins and'blts for 'thelinksfand'levers Will not 'interfere with its movement when 'it is A'fully retracted.

One of theV important vadvantages of `my invention is thatitcan -bemaiiufactured very easilvand cheaply -ofliea'vy sheet 'metal and practically all of tthe Vparts can `be ,stamped out. Furthermore,theattachmentito a Window or-other shutter can beniade'veryeasily and-quickly by any lunskilled laborer. The 'parts ara-very simple and can easily `vbe V'removed for repairs. `All off 'the operating mechanism is lprotected :trom *the YWeather Eby the housing. The operati-ng mechanism, be- 'ing made almost 'entirely of sheet metal parts, 'can the fhoused l'in a `very 'small space. YHaving thus'descrbed 'the `preferred `embodiment of :my invention Without limiting myself ltheretofwhat I claim and desireto secure by `|Letters 'Patent ;is;:
